From the construction describedit willbe seen that the beam is`connected with! the frame' 'of the machine'by a system of linksconstituting a .para`llel' motion`, which, while permitting the beam tobe shiftedlaterallyendwi'se, willmaintain it parallel with theA axle,with'the shovels facing squarely in the direction inthe line' ofdraft.

The' foot-lever mechanism for 'controlling thc"`lateral movements of thebeam constitutes the' main feature of my invention and' consists of twohorizontal' arms A and B',

fixed' at' theirfro'nt ends" to the' two fore-'and'-of-the-twoadjaadapted tol cooperate withla 'se 24, iixed" fto 'theframe-bars, lever extending in iront'v of the drivers seat, but` within'easy reach of the-drivers operation of the lever the beamniay'be'ladjuste'd'vertic'ally with reference lto he vframe andlocked-inits adjusted position, purposes of 'transportation the bea v may bel.sition. f In order that-the'inclination ofthe culti'- vating deviceswithreference tothe surface ofthe 'ground may I e depth of cut, Iprovide for a bodi y adjustment of the transverse fbeamfarounda'horizontal .transverse axisthe draft-links, so'that theI bladesmay-,be tipped upward'v or. set at' intermediate points, the conditions4,to be met. vThis is 'eff aft straps 17D, respectively, cent draftdevices' near the front ends' of said stra s, whence the arms areextended diagona ly 'rearward' 'in' 'oppositel directions and cross eachother and have their rear ends arranged'eac'h'oyer the vothers strap,which rear ends arejprovidedwithifoot-rests a and l) to receive the feetof the driver, by means' of i which by applying vpressure,l of the armshe isv enabled'to shift the' beam laterally' and maintainit'undnerperfect control. To the under sides' of the' arms, ata; point"just forward of the foot-rests, there are journaled on horizontalyz,transverse axes friction-,rollers 'a' and'tv, which" `as vthe 'beamand" its fore-and-'aft links move vlaterally7` bear 'and travel on theunderlying straps, and thus relieve the lrelatively moving parts Aoffriction andrender their movements easy and sensitive.'

It will be seen from the construction described vthat the'forwardjendsof'the'l footlevers `are connected adjacent the pivotal connectionof'the draft 'devices with the axle and that 'their rear ends 4'arearranged to'the'side'of the axis and distant from it', `with'thefoot-rests so disposed thata forward pressure of thedrivers feetwill apply a" lateral strain on the draft :devices under a or downward lected by' the-- manner of connecting' the bearingsleeves 19' .ingprovided' with a dependingl extension 19, seated against the -lug16clIof 'the bracket arid pivotally beamte be'tipped or' rocked withreference tothe bearinglsleeve's.

In a machine of this typey the, crossedfoot-levers or arms A B are applied to' the beams which correspond tothe draft devicesof the beet-.cultivator first described, theconnecting-link'D corresponding to the transverse connecting-beam -13 ofthe cultivator first described. While in a cultivator of this type withthe shovels mounted on the drag-bars the shovels will not standsquarely'in the line of draft when the drag-bars are inovedlaterally,their position will not be such as under certain conditions wouldinterfere materially with their functions.
